HERMAN CAMP, OF SAN FRANCISCO, CALIFORNIA.

IMPROVEMENT IN QUARTZ-CRUSHERS.

Specification forming part of Letters Patent No. 45,698, dated January3, 1865; antedatcd September 17, 1863.

To all whom it may concern Be it known that I, HERMAN CAMP, of

i the city and county of San Francisco, in the State of California, haveinvented a new and useful machine for pulverizing and grinding minerals,ores, and other substances, entitled Camps Revolving Quartz-Crusher, andI do hereby declare that the following is a full, clear, and exactdescription'of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,in which- Figure 1 represents a perspective view of the entire crusher.Fig. 2 shows an end or side view of the smaller cylinder,friction-rollers, frame-work, and pulley. Fig. 3 exhibits a series ofdies, so that when the same are bolted or screwed together they willform the entire surface of one or more cylinders, with its intersticesor indentations. Fig. 4 represents a perspective view of the dies andtheir interstices, and the manner of its construction. Fig. 5 shows aperspective view of similar dies,

showing the the mode of construction with diagonal interstices. Fig. 6illustrates the internal construction of the head-piece, and the bucketsor cups for transmitting the ore or other substances while revolvingbefore the inner or smaller cylinder, also an aperture for receiving ahopper.

The nature of my invention consists in providing a cylinder or cylindersof any desired length or dimension, and of such material as may be bestsuited, placing therein a roller or crusher, or a series of diescomposing such roller when bolted together, provided with interstices orindentations, which will serve in transmitting the ore or othersubstances to be pulverized before the roller, while the same is inmotion, and that the whole crushing apparatus may rest and revolve uponfour or more friction-rollers.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

Arepresents the cylinder, made ofiron and of any desired length ordimension. To theinner surface thereof a series of chilled iron'stavesare screwed or bolted. Should the same become worn out, this surface maybe replaced by a new set of such staves, j. On the outside of saidcylinder I provide guides or flanges to keep the friction rollers intheir place. The yellow-colored end of said cylinder shows a bolt orsieve. As the crushed ore or substances escape from the cylinder it maybe bolted and collected by any of the known means. The head-piece B ismade of similar material, and is securely fastened by bolts and screws.The same is provided with an aperture or loose collar for the receptionof the hopper C, by which latter said cylinder is fed,

70 It In Yo represent four friction-wheels, upon which the cylinderrevolves or rests. These are securely placed upon the frame D.

l) is a belt encircling the cylinder and pulley d. I do not, however,confine myself to the manner of propelling the same.

0 0 represents cross-bars or bolts placed transversely for the purposeof preventing the rollers or crushcrs, Fig. 3, from slipping out of thecylinder.

In Fig. 2 I show sections j, representing the staves or grindingsurfaceof the cylinder A.

Fig. 3 illustrates the sections and dies of the rollers or crushers asplaced inside of cylinder A, and are about one-fourth the size less thanthe diameter of said cylinder.

Fig. 4: represents the precise manner of the construction of saidpieces-namely: g are a series of sections of cast-iron, provided withdovetail joints for the reception of the accompanyin g dies f, which aremade of chilled iron. All of these sections are cast with holes in thecenter, so that they may be bolted or screwed together. The buckets orcups 0 are for convcyin g the partially crushed ore from the back ofsaid crushers to the front thereof. Fig. 5 is in reality the same rolleror crusher in point of construction or application, and the onlydifference is that the cups or buckets are placed diagonally to hastenthe conveying process of the pulverized substances till it is dischargedinto the sieve or bolt. 0n the inside of the head piece B, Fig. 6, areshown a series of buckets, 13, provided therein for the purpose ofconveying the uncrushed substances on the crushing-surface and beforethe crushers or rollers.

I do not confine myself to the manner of propelling the crusher.

The grinding-surfacesj and f,when worn out, may be replaced by theircorresponding pieces,

What I claim as my invention, and desire whole made, constructed, andoperating in the to secure by Letters Patent, is-- manner and for thepurpose herein described.

The combination of the cylinder A and its peculiarly constructedhead-piece B with the HERMAN CAMP dies, constructed of a series ofsections ofcast- Witnesses:
